Serial No. 576,505.

To all whom it may concern:

Be it known that I, Josnrrr E. J ONES, a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Oil-Filters, of which the following is a specification.

My invention relates to improvements in oil-filters, more especially for cleansing and purifying waste oil which has been used in lubricating machinery or for other purposes, and has for an object to provide a device which is simple in construction, inexpensive to manufacture, effective in use, and which will remove all dirt or other foreign matter from the oil and clean and deliver the oil in a purified state.

A further object of this invention is to provide a device of the above character, which is so constructed that desired parts of the same may be readily removed for the purpose of cleansing.

A further object of my invention is to provide a filter which may be employed to render the purification of oil continuous.

My invention consists generally in the arrangement and combination of parts to be hereinafter described.

In the accompanying drawings forming a part of this specification, and in which like numerals are used to designate like parts throughout the same, Figure 1 is a central vertical longitudinal section through the filter. Fig. 2 is a side elevation of the filter. Fig. 3 is a horizontal section taken on line 3-3 of Fig. 1. Fig. 4 is a vertical section taken on line 4-4 of Fig. 1, and Fig. 5 is a vertical cross section taken on line 55 of Fig. 1.

In the drawings wherein is illustrated a preferred embodiment of my invention, the numeral 1 designates a preferably rectangular casing of the filter, which is shown as being divided into a plurality of compartments 2, 3 and 4, by means of dividing walls 5 and 6. This casing, as shown, is arranged upon a suitable base 7 formed out of transverse beams 8, upon which are disposed,

planking 9.

The walls 5 and 11 of compartment 2 extend above the casing 1, as shown and carry a cover 10. The upper extended portions of the walls 5 and 11 are engaged upon one side by a stationary wall 10 and upon the opposite side by a downwardly swinging door 1O which is hinged to the casing 1 as shown at 11*. The upper end of the door 10 is provided with latches ll having lugs which engage the brackets 12 fixed upon the strip 10*. Within the upper portion of the compartment 2 formed by the upper extended portions of the walls 5 and 11, are arranged horizontal superposed spaced brackets 12, 13 and 14, which are rigidly secured to the walls of the compartment. A strainer 14 is disposed upon the bracket 12 and comprises a tray 15 having its bottom formed of fine wire mesh as shown at 16: Below the strainer 14 is a strainer 17 comprising a tray 18 which is supported by the bracket 13. This tray 18 has its bottom formedof straining material, as shown at 19. This straining material 19 may preferably be formed of coarse wire fabric, which is covered with suitable form of cloth. Below the strainer 17 is a conveyer pan 20, which is disposed upon the bracket 14 as shown. This conveyer pan has its bottom 21 inclined and provided with an opening 21 to deliver material within an oil passage 22, as shown.

By the construction of the above referred to parts it is obvious that the door 10 may be released from the cover 10 and swung downwardly to permit of the removal of strainers 14 and 17 and the pan 20. The oil passage 22 is formed by a wall 23, which is substantially U-shaped in cross section and suitably secured to the wall 11, as shown at 24. The wall 23 is vertically disposed and terminates in a horizontal discharge mouth 25, which is spaced from the bottom of the compartment 2, as shown. The compartment 2 is provided adjacent the discharge mouth 25 with brackets 26, for removably supporting the perforated curved plate or spreader 27. This perforated plate is provided with a suitable cut-out portion 28 to receive the wall 23, in order that the oil or the like may be delivered from the discharge mouth 25 below the spreader 27. This perforated plate is also provided with a handle 27 A feed pipe 29 is preferably vertically disposed and passes through an opening in the cover 10, to deliver material within the uppermost strainer 14 An inverted U-shaped pipe 66 is provided, and passes through the wall of the casing 1 to have its short arm disposed within the com partment 2, as clearly illustrated in Fig. 5. The free end of this short arm is spaced from the bottom of the compartment 2 and preferably terminates below the spreader 27. The long arm of this pipe is disposed out wardly of the casing 1 and extends clownwardly, forming with the short arm, a siphon.

The wall 5 is provided near the pan 20 with an opening 35, which is arranged a little below the upper end of the oil-passage 23. This opening establishes communication between the compartments 2 and 3. A wall 36, which is substantially U- shaped in cross-section, is vertically disposed within the compartment 3 and is suitably secured as shown at 37 to the wall 5. This wall terminates as shown at 37*, and is accordingly spaced from the bottom of the compartment 3. Centrally within the compartment 3 is arranged a coiled heating pipe 39. The wall 36 cotiperates wit-h Wall 5 to form a passage 38, for feeding oil from the opening 35 to the lower portion of the compartment 3. The coil pipe 39 is vertically arranged and has its upper and lower ends suitably connected to pipes 40 and 42, by means of couplings 43 as shown. The pipes 40 and 42 extend through the walls of the casing 1 and form a steam tight joint therewith by means of clamping rings 44. Steam is fed into the coil 39 at its upper end and discharged from the same through its lower end. A strainer 45 is arranged in a substantially vertical position within the compartment 3 and near the upper end of the same as shown. This strainer comprises an approximately semi-circular base 46 upon which are formed upstanding strips 47. The side' of the strainer 45 as shown is formed of straining material 48 which is secured to the strips 47 and the base 46 in any suitable manner. The straining material, 48, is preferably formed of a coarse wire fabric upon which is arranged a suitable form of cloth. The base 46 is provided at its end with a vertically disposed flange 49 adapted to be removably supported within a bracket 50 secured upon the wall 6. The strips 47 formed upon the base 4.6 are removably mounted within brackets 51 which are suitably secured to the wall 6, as clearly shown in Fig. 3. It is thus seen that the strainer 45 is removably mounted within the compartment 3, whereby the same may be cleansed when desired. The wall 6 is provided near its upper end with an opening 52 which communicates with a horizontally arranged chute 53, which in. turn is adapted to feed material to a strainer 54 arranged within the upper portion of the compartment 4. The strainer 54 comprises a tray 55 upon which is formed a flange 56, which is removably arranged upon a bracket 57 suitably secured to the walls of the compartment 4. The tray 55 has its bottom formed of straining material as shown at- 58, and this straining material is preferably formed of coarse wire fabric covered by cloth or the like. The compartments 3 and 4 are provided with a common cover 59 which is readily removable.

The casing 1 is provided as shown with a plurality of tube-gages 59, 60 and 61, which communicate respectively with the compartments 2, 3 and 4. The function of these gages is to show the level of the liquid within each of the compartments. The casing 1 is further provided near its bottom with spigots 62, 63 and 64, which communicate respectively with the compartments 2, 3 and 4. By the employment of these spigots the liquid may be drawn from either of the compartments 2, 3 and 4 when desired. The compartment 4 has communicating therewith a spigot 65 which is arranged as shown above the spigot 64. The casing 1 is further provided as shown at 67 with means for connecting a suitable pipe to the same for communication with the compartment 4. This pipe is to be employed when the filter is used to continuously purify oil.

In the operation of the filter the oil to be purified is fed through the pipe 29 into the upper filter 14 and passes through the fil tering material 16 to the filter pan 18 and through the filtering material 19 to within the pan 20. The oil then gravitates down the bottom of the pan 20 and is discharged within the oil-passage 22. The compartment 2 contains water as shown, and when the oil is discharged within the compartment 2 below the perforated plate 27, such oil will travel upwardly through the perforated plate toward the discharge opening 35. The oil when passing through the perforated plate 27 is broken up into small globules, and the oil in this condition travels upwardly through the water and is thoroughly washed of the impurities which were not previously taken up by the strainers 14 and 17. The oil then travels through the opening 35 and downwardly within passage 38 to be discharged within the compartment 3. The oil while in compartment 3 is subjected to a proper amount of heat given out by the coil 39 and in this heated state the same may be deprived of further of its impurities. As the oil rises within compartment 3 the same passes through the strainer 45 and through the chute 53 into the strainer 54. The oil finally passes through the straining material 58 of strainer 54 and is collected within the compartment 4, where the same may be almaterial should be two or more different kinds of oil, such heat would cause a thorough mixing of said oils. The oil may be withdrawn from the compartment 4 through either of the spigots 6 k and 65, the spigot 64 however being designed especially for the removal of sediment.

It is to be understood that the form of my invention hereinabove described is to be taken as a preferred example of the same, and that certain changes may be made in the same without departing from the spirit of my invention as set forth in the appended claim.

Having fully described my invention, I claim In a device of the character described, a shell divided into a plurality of compartments, the first compartment extending upwardly above the others and having one side thereof formed open, a door hinged to said first compartment to normally close the open side thereof, a plurality of spaced superposed strainer devices disposed within the first compartment and adapted to be readily removed therefrom 'through the open side thereof, a conveyer pan disposed within said first compartment, arranged below said strainer devices and adapted to be removed therefrom through said open side, a vertical conduit disposed to receive oil from said conveyer pan and discharge the same into the lower end of the first compartment, a strainer removably mounted in the lower end of said first compartment and disposed above the discharge end of said conduit, said strainer being in the embodiment of a plate curved in cross-section to provide the greatest area and perforated throughout, whereby the oil is separated into fine particles when passing therethrough, a second conduit disposed wi hin the second compartment and adapted to convey oil from the upper end of the first compartment and discharge the same into the lower end of the second compartment, a heating coil arranged within the second compartment, having its turns substantially horizontally disposed and the inlet end arranged above the outlet end, whereby the condensed steam or water will run out of the coil and not seal the same, a conduit for discharging material from the upper end of the second compartment into the upper end of the third compartment, a removable strainer device disposed in proximity to the last named conduit and being curved in cross-section to afford the maximum area, and a removable strainer device disposed in the upper portion of the third compartment to catch material delivered through the last named conduit.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH E. JONES.
